As a freelancer, you process personal data daily. GDPR sets clear requirements for handling it.
GDPR Principles
- Lawfulness: You need a legal basis (contract, consent, legitimate interest)
- Purpose limitation: Use data only for stated purpose
- Data minimization: Only collect what you need
- Storage limitation: Delete when no longer needed (but observe retention periods)
Practical Implementation
Collecting Data
Only necessary fields: Name, address, email. No unnecessary data.
Storing Data
Secure systems, encrypted connections, regular backups.
Sharing Data
Only with legal basis, conclude DPA with service providers.
Retention Periods
| Document | Period |
|---|---|
| Invoices | 10 years |
| Contracts | 10 years after end |
| Emails | 6 years |
